A fast-paced reflex game built with Odin and Raylib. Pilot a neon square through a cyberpunk grid and link up with glowing targets as quickly as you can.

You control a cyan neon square on a dark, scrolling grid. A pulsing target appears somewhere on screen — reach it before the timer runs your patience dry. Each successful collision counts as a link, resets the clock, and spawns a new target somewhere else in the arena.

The goal is simple: chain links together and beat your personal record.

New targets always spawn at least 220 pixels from the player, so you won't get cheap instant re-hits that skew your record.

• Cyberpunk visual style — deep navy background, electric blue neon palette, CRT scanlines, and sci-fi HUD panels
• Neon glow rendering — additive blend layers simulate bloom without custom shaders
• Animated perspective grid — scrolling floor grid with depth-based line weight
• Motion trail — fading afterimage follows the player
• Particle bursts — explosion of neon sparks on each link
• Screen flash — brief cyan pulse on collision for hit feedback

This project is a single-file game written in Odin using Raylib via Odin's official vendor:raylib bindings.

Odin is a general-purpose language focused on high performance and clean syntax. For a small game like this, it offers:

• Structs and procedures for clear game-state modeling (Player, Target, Game_State)
• Compile-time constants for tuning values (MIN_SPAWN_DISTANCE, color palette)
• No runtime overhead — the game loop runs natively with minimal abstraction
• Built-in math via core:math for movement, pulsing animations, and spawn distance checks

Raylib handles everything graphical and interactive. The game uses it for:

The render loop follows the standard Raylib pattern:

Update game state  →  BeginDrawing  →  Draw everything  →  EndDrawing

All visual effects are procedural — no external assets, textures, or fonts are loaded. The neon look is built by layering semi-transparent shapes with additive blending.

• Odin compiler (dev-2026-06 or later)
• Raylib (bundled with Odin's vendor:raylib — no separate install needed)

Everything lives in main.odin. The file is organized into:

1. Constants & types — palette, particle limits, game structs
2. Rendering helpers — neon shapes, background grid, HUD, scanlines
3. Game systems — particles, trail, target spawning
4. main — initialization, input, collision, and the frame loop
